Historically, some 2000 years ago, the Greek merchants were represented by envoys in some ports of commerce to organize the business transactions between sellers and buyers. They gave themselves rendezvous in secret locations for transhipment of cargo and port charges to escape. The idea of tax havens was born.
Closer to home, here are a couple of decades, some countries provide tax benefits such as: Switzerland, Liechtenstein, the Channel Islands, Bermuda, Cayman Islands, Panama, etc..
Since then, many others have adapted their tax laws to attract international trade on their territory, removing trade barriers, abolishing exchange controls practically, and providing guarantees for lower taxation, or even zero!
You want to make money by protecting it, you're right! You can perfectly legally and perfectly fit a structure abroad, while remaining in France or Belgium, ie, to trade here, and send money there. However, it does not do anything, anyhow, and at any price.
